Fleets doesn't give drachma

So, I was just sitting on a server upgrading my fleet and boom, fleet log stops showing my drachma gains. At that moment I had 2 recovery, 1 plunder and 1 trading task. I tried rejoinning and changing all of my tasks, but nothing helped. I had to pause my fleet’s work and looking for help now. I cannot report it as a bug since I could never find moment when bug tickets are not overflooded.

that’s weird, it’s working just fine in my server

So uh, I found the solution. Idk what is the formula behind minimize risk, but it is broken. After certain amount of active followers (around 5k?), fleet started to use all earned profits to repair itself, giving me nothing in return, besides it would still leave some ships damaged, so I have to pay for them from my pocket. I switched to maximize risk and fleet returned to normal work.

Minimize risk doesn’t actually repair fleets it just buys supplies and food
